Abstract: 1533557 Adjusting response of linear fluid vibrators GRUMAG GERATE-UND MASCHINEN GmbH 11 Nov 1975 [12 Nov 1974] 46579/75 Heading F2S In a linear fluid vibrator, of the type where the piston 2 has a rod projecting from the cylinder 1 for attachment to the member to be vibrated, the mass of the cylinder can be adjusted to vary the response of the vibrator. The mass of the piston may be adjusted in the same way. The piston and cylinder may be made of light material, e.g. plastics, and different auxiliary masses 3, 4, 4a bolted on for different applications. The auxiliary mass may instead be an adjust. able volume of water or mercury supplied to an extension 4a<1> of the cylinder (and possibly also to the interior of the piston). Instead of fluid supplied to one side of a spring biased floating piston 4c<1> (as shown) fluids of different densities may be supplied, one to each side of the floating piston. The piston-cylinder vibrator operates in the usual way, compressed air supplied at 1b and exhausted at 1a causing the piston to reciprocate.

Abstract: 1,199,977. Grinding; rectilinear spacing; gauging. LANDIS TOOL CO. 18 Oct., 1967 [18 Oct., 1966], No. 47353/67. Headings B3B and B3D. In a machine tool, such as a cam-shaft grinder in which the workpiece W is moved from one grinding position to the next, the plunger 23 of the indexing mechanism is guided towards and away from notches 21 in a spacing bar 20 by means of spaced pivoted members 26, 32. As shown, the spacing bar is fixed to a workpiece carriage 7 which is traversed by fluid pressure supplied through hollow fixed piston-rods 15, 16. The hydraulic circuit includes a pump P, a piston valve 47 and a valve 18 having a stepped cylinder for a piston 41 and a valve member 37 spaced apart by a compression spring 42. When start lever 64 is actuated, fluid is supplied through line 62 to move the piston, spring and valve member 41, 42, 37 against the tension of a spring 43, the movement causing a lever 30 to pivot about a pin 31. Fluid passes via line 65 to the carriage cylinder 12 to advance it to the right, the plunger 23 being urged into the first notch by the lever 26 which is pivoted about a pin 28 by a tension spring 50. The plunger is then carried to the right by the spacing bar, the movement causing the levers 26, 30 to pivott clockwise in order to operate a switch controlling the advance of a grinding wheel 11 and to cause the return of the valve member 37 for stopping the fluid pressure advancing the carriage. After the first cam has been ground, a solenoid valve 58 actuates the delivery of fluid pressure to the piston valve 47 to cause lever 26 to pivot anti-clockwise and disengage the plunger. The spring 42 moves the valve member 37 to continue indexing the carrier to the next position. The piston 41 remains under pressure until all the cams have been ground, the fluid pressure on the piston 41 then being removed and fluid supplied to the other side of the cylinder 12 to reset the carriage to the left. The plunger 23 is set to tilt slightly upon being disengaged to reduce friction; after disengagement, lever 30 pushes the plunger out of alignment to prevent it returning into the same notch.

Abstract: 1,159,587. Automatic control systems. A.W. SCOTT. Oct. 21, 1966 [Oct. 23, 1965], No. 47415/66. Heading G3R. [Also in Divisions H1 and H5] In a micro-wave generator for an oven (see Groups H1 and H3-H5) in which an electron beam is focused along a path adjacent a slow wave structure with which it interacts, changes in the power output of the tube are counteracted by automatically adjusting the spacing of the electron beam from the slow wave structure. The variation of resistance with temperature of of a thin tungsten wire 141 included in the output lead of the tube unbalances the bridge 140, the resulting output from the bridge being applied across electrodes 147, 148 to deflect a secondary beam constituted either by a separate electron beam passing through the tube, or by an edge of the main beam. The deflection alters the ratio of beam current collected by the two plates 151,152, the resulting variation in potential difference across resistor 155 being applied to main beam deflection electrodes 104,105 to control the spacing of the main beam from the slow wave structure.

[Also in Division F2] In a collapsible steering column for a vehicle, upper and lower shaft portions 4, 10 are slidably connected, a jacket assembly 12 rotatably supporting the upper shaft portion 4 includes an upper tube 22 which is adapted for mounting so as to be slidable only in a downward direction in a clamp 30 integral with the vehicle body and is connected by deformable energy-absorbing means B to a fixed lower portion 38, and the lower shaft portion 10 includes a flexible member C capable of transmitting only rotational torque, whereby the energy of a downward impact caused by the driver's body is absorbed and displacement of the upper part of the column by a rearward impact is avoided. The bracket 30 includes a rubber or plastics bearing 34 having a low co-efficient of friction. A ring 24 co-operates with a groove 26 to locate the shaft portion 4 axially of the tube 22, and a shoulder 36 prevents rearward displacement of the tube 22 in the bracket 30. A flange 48 prevents rearward displacement of the lower shaft portion 10. The energy-absorbing means B may comprise a collapsible bellows tube (Fig. 4, not shown), inner and outer tubes formed respectively with pins and with slots deformed by the pins upon relative axial movement (Figs. 5, 6, not shown), or an outer tube having a die at one end receiving a reduced portion of an inner tube (Fig. 7, not shown).

Title: Process and apparatus for treating wood
IPC: B27K3/10
Filed: 1965-11-10
Abstract: One or more logs are placed in a chamber (10) having a porous wall (13) which acts as a filter, one end of the logs being in contact with liquid in the chamber and the other end being in close contact with the porous wall and embedded in a filter cake (28) formed by filtering a slurry through the porous wall, and a difference in pressure is applied between the two ends of the logs such that liquid is forced longitudinally through the logs and out of the chamber through the porous wall.  The pressure difference may be up to 1,000 psi.  A positive and/or negative pressure, respectively, may be applied to the liquid and porous wall.  The porous wall may consist of a layer of fabric supported on a porous plate.  The filter cake may have a finer layer surrounded on a coarse layer to produce a good seal.  The slurrying liquid may be the same as or different from the impregnating liquid.  The method may be used for impregnating logs with liquid so as to proof them against fire, chemicals, decay, or physical distortion.  In a modification, logs may be dried without impregnation by employing hot liquid at a pressure only sufficient to prevent vapour passing out into the liquid.  In another embodiment (Figs. 6 and 7), one end only of a log is contained in a chamber (88), the intervening space being filled by a filter cake (99) which acts as a seal, the porous wall (97) being replaced by a cap (101) carrying an inlet pipe (102) for supply of the impregnating liquid.

In an instrumentor measuring the roughness of paper the sheet of paper 10 is held against a measuring head 1 by a movable backing member 8, the head being divided into inlet chambers 20 and outlet chambers 21 separated by lands 19, the inlet chambers being connected to a source of fluid pressure 40 (see Fig. 4, not shown) and the outlet chambers to flowmeters 65-67 (see Fig. 4). The backing member 8 may be a flexible diaphragm and is raised against the paper by increasing the pressure in a chamber 12 disposed beneath the member. In use, fluid at the required pressure is fed to the backing member 8 and to the head 1, and through inlet channels 20 to the surface of the paper 10. The roughness of the paper is measured as a function of the gap between the edge of the lands 19 and the surface of the paper, and this is determined by the outlet pressure reading on the flowmeters. Instead of the chambers being arranged concentrically, the chambers may be formed by a plurality of spaced parallel plates.
